Morphology | Morphometrics
(total): 14 - 17;
soft rays: 16 - 19. Brown to reddish with yellowish patch on top of head, triangular black markings along belly, and blackish anal and caudal fins (central portion and margin of caudal fin lighter). Male with black "mask" covering front and lower two-thirds of head. Dorsal rays III + XI-XIV + 8-10; anal rays I,16-19; pectoral rays 16-17; pelvic rays I,2; lateral line interrupted, 15-19 + 14-19; head, chest, and pectoral-fin base scaleless; short orbital tentacle present; mandibular pores 3-5 + 1 + 3-5. Maximum size to 2.8 cm TL (Ref. 90102).
Adults are found in rock and coral reefs 5 m or shallower (Ref. 90102). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00246 - 0.01227), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
